Title: Improvements in or relating to electrical waveguides
Inventor: COLLARD JOHN
IPC: H01P7/06
Filed: 1948-03-25
Abstract: 649,732. Wave-guides. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 25, 1948, No. 8746. [Class 40 (viii)] A tuning piston for a non-circular wave-guide is arranged close to the guide surfaces in which maximum current flows, but more widely spaced from the other guide surfaces. A rectangular wave-guide 1 has a cylindrical piston 2, integral with an adjusting screw 3, and arranged to be close to the middle of the broad. sides. The piston can rotate in the guide and is provided with annular quarter-wave slots 4, spaced apart by a quarter wave-length, to prevent energy flow in the co-axial circuit formed by the guide and the piston. The slots may be arranged obliquely to the piston axis, or may be filled with dielectric.

Abstract: 1,117,575. Crucibles. WIENER SCHWACHSTROMWERKE G.m.b.H. 24 Feb., 1967 [25 Feb., 1966], No. 8891/67. Heading F4B. An induction heated crucible 2 is tilted about an axis 4 near the lip 3 for pouring metal, and is tiltable about a second axis 17 near the outer end of a slag gutter 11 to pour off slag. The axes 4, 17 are parallel, and locking members 21 22 are linked together and operated to prevent the pivots lifting out of the bearing about which the crucible is tilted. A slag bucket 14 is pivoted to the casing of the crucible so that slag is not spilt when metal is poured. To pour metal the crucible 2 and casing are tilted, but to pour slag the crucible 2 is tilted relative to the casing. Covers 6, 9 for the crucible and slag gutter, are arranged to be swung away when the slag is poured. In a modification, (Fig. 3, not shown) the slag bucket is pivoted to the furnace support structure, and a working platform extending over the slag bucket is swung away before the metal is poured.

Abstract: 1,017,076. Lasers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 25, 1963 [March 8, 1962], No.8927/62. Heading H3B. A cylindrical ruby laser has a reflecting system comprising a convergent lens 5 and a spherical mirror 7. The ruby 1 has parallel and optically-plane end surfaces 2, 3 normal to the principal axis and is stimulated by a high intensity light .source 4. The centre of curvature of the mirror is in the focal plane 6 of the lens, a limiting aperture 6A being provided to control divergence of the laser beam. Optionally, control devices such as choppers may be located either at the focal plane or between the focal plane and the mirror. The coherent laser light is emitted along the principal axis in the direction B, either the ruby surface 3 being made partially reflecting or a separate partially-reflecting surface 3A being provided. The arrangement suppresses off-axis modes, but if such modes are to be propagated the partially-reflecting surface 3A and the mirror should be at conjugate foci of the lens 5.

Title: Apparatus for spraying or pouring varnish
IPC: B05B13/02
Filed: 1958-03-20
Abstract: <PICT:0840410/III/1> <PICT:0840410/III/2> Apparatus for pouring or spraying varnish comprises a rotatable shaft adapted to receive a body to be varnished, and having thereon a cam, rotatable with the body, with a periphery accurately corresponding with the contour of the body; a driving pulley rotatable at constant peripheral speed and adapted to rotate the body; and means for urging the cam and the pulley towards one another so as to keep constant the distance between the surface of the body and a pouring or spraying nozzle.  As shown in Fig. 1, two plates 3 and 4 are connected by two vertical rods 5 and are rotatable about a column 2 by bevel gears 17 and 18 and a motor 19.  Slides 6, 7 are non-rotatably mounted on the rods 5, and each supports a pivot pin attached to a cam 9 on which is mounted a block 12 for supporting the body 10 to be coated.  The periphery 9a of each cam 9 reproduces the cross-section of the body 10, and belts 22 are trained around the cams 9, driving pulleys 25 or 25a and guide and tensioning pulleys, not shown. When a body 10 is brought into operative position beneath the nozzle outlet of a tank 30, by operation of the motor 19, a plunger 13 of a pneumatic cylinder 14 contacts a projection 16 on the respective slide 6 and urges the cam 9 against the pulley 25 or 25a which is then driven by a motor 26 through a gear 27 and clutches 28.  A displaceable varnish deflecting dish 33 and collector channel 34 are provided beneath the tank 30, so that the application of varnish may be interrupted rapidly.  In a modification, Fig. 3, the cam is rotated about a fixed axis by a pulley 38 on a swivelling arm 39, connected by a rod to a varnish pouring vessel 30a, which is suspended from two parallel arms 42. The pulley 38 is driven by a motor 43 via belt 34.  The varnish may be sprayed instead of poured.

Title: Electrical signal transmission system
IPC: H04Q1/442
Filed: 1942-07-09
Abstract: 554,786. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). July 9, 1942, No. 9540. [Class 40 (i)] [Also in Group XXXIX] In an arrangement for signalling over a circuit which may form part of a telephone connection, synchronous impulses are created at the transmitting and receiving ends and a counting switch stepped by the impulses at the transmitting end determines the duration of transmission of continuous A.C. to the receiving end to render effective a certain number of the impulses thereat. As shown, the impulses are supplied by generators IMP1, 2 which in the case of signalling within an exchange may consist of cams mounted on a common shaft. When the generators are located in different exchanges they may be synchronized by known methods. Signalling is started by the closure of contacts St1, 2 at the two ends, whereupon IMP1 controls relay B3 and IMP2 steps the switch SS. As soon as the latter moves offnormal, A.C. preferably of .voice frequency is sent over wire X of the connection and, through a transformer T, causes a cold-cathode tube L to strike, thereby putting relay B4 under the control of B3 to repeat impulses. When the switch SS reaches a marked contact, relay B2 energizes and cuts off the A.C. to terminate the repetition of impulses.

Abstract: The invention comprises pyrazolone derivatives of the general formula:  <FORM:0843690/IV(b)/1> (wherein R1 represents an alkyl group of 1-4 carbon atoms, R2 represents hydrogen or an alkyl group of 1-4 carbon atoms, and R3 and R4 are similar or dissimilar and each represent hydrogen, an alkyl group of 1-4 carbon atoms, an alkenyl group of 2-4 carbon atoms, or a phenyl, benzyl, nitrophenyl, chlorophenyl or tolyl group, or R3 and R4 jointly represent a -CH2-CH2-CH2- linkage forming a five membered ring with the adjacent carbon atoms), and their physiologically acceptable acid addition salts, and the preparation thereof by condensing a piperidyl-4-hydrazine of the general formula:  <FORM:0843690/IV(b)/2> with a b -keto-acid or functional derivative thereof of the general formula:  R3-CO-CHR4-COX (wherein X represents a hydroxy group, an alkoxy group of 1-6 carbon atoms or a primary or secondary amino group), followed, if desired, by salinification with an acid.  The condensation is preferably effected in the neighbourhood of ambient temperature in an inert solvent, which may subsequently be removed by vacuum distillation.  When R2 is other than hydrogen it usually yields a mixture of isomers, which may be separated if desired.  The products are useful as antipyretic and analgesic agents, or as intermediates therefor.  a -Butyrylphenylacetic acid ethyl ester is prepared by the action of ethanol and hydrogen chloride on a -butyryla -phenylacetonitrile, which in turn is prepared by condensing ethyl butyrate with benzyl cyanide in the presence of sodium ethoxide.  Specifications 632,832, 843,688 and 843,689 are referred to.
